Book Description
The Arctic Cod: A Study of Research into the British Trawl Fisheries discusses trawl fishing in the North Sea. The book reviews the history of trawl fishing from the seventeenth century until the mid-nineteenth century when it developed into an industry. Scientific studies of the Artic cod begins in 1860 when the Norwegians started keeping record of their catches at Lofoten. Britain starts to keep reliable records of catches in 1929; and the first study of the Artic cod was by Michael Graham in 1949, done in three ships, the R.V. Ernest Holt, G.O. Sars, and Johan Hjort. The book describes the research work done on the R.V. Ernest Holt at the cod grounds near Bear Island. The Artic cod lives in the Barents Sea and spawn in the Vestfjord; it travels between 1,000 and 1,600 miles each year between its feeding and spawning grounds. The text also describes how the study is undertaken at sea including monitoring temperature measurements, mesh-size, blood samples; and of carrying on studies of fish on the markets, such as recording the number of boats catching what kind of fish. The text also discusses the future of fisheries research in the international arena. This book is suitable for marine biologists, environmentalists, marine conservationists, and researchers interested in marine science.

Book Description
The joint management of Norway and Russia in the Barents Sea has been successful in conserving the living marine resources and is a major factor contributing to the present rich fisheries in the area. The basis for this conservation success is scientific research, which, to a large extent, has been conducted through a long-lasting co-operation between Russian and Norwegian scientists that has expanded greatly over the past half century. Based on joint Russian-Norwegian authorships, this monumental book celebrates the scientific co-operation by reflecting on the historical development and the scientific methods applied, and by offering a comprehensive presentation of the vast knowledge of the Barents Sea resources and ecosystem obtained through these co-operative efforts.

Book Description
A comprehensive handbook, covering all aspects of the Atlantic cod including the biology, ecology, life histories, behaviour, commercial exploitation and conservation Not only is Atlantic cod one of the most valuable food fish in the world’s oceans, it is an important component of North Atlantic ecosystems and has been subject to much research into its biology, ecology and exploitation. After hundreds of years of exploitation, overfishing in the last half of the 20th Century caused many stocks to collapse, most famously the Northern cod stock off Newfoundland and Labrador, Canada. Since then, most cod stocks have been better researched and managed, but remain in a variety of states, from fully recovered to continued decline. This book, written by world experts, describes that research and management, and the importance of cod and its fisheries on North Atlantic cultures and economies, with impacts well beyond the range of the species. Atlantic Cod: Bio-Ecology of the Fish offers insightful chapter coverage of cod nomenclature, taxonomy, phylogeny and morphology; physiology and ecophysiology; reproduction and spawning behavior; early life history and pre-recruitment processes; migrations, movements and stock identity; feeding, growth and energetics; the place of cod in the ecosystem; the exploitation of cod through history and present day commercial fisheries and precautionary management for sustainable fisheries; impacts of climate change on cod biology and ecology; and the future of the species and its fisheries. Discusses the major commercial importance of Atlantic cod through history Provides a comprehensive treatment of the bio-ecology of the most researched and highly exploited fully marine species Examines how the decline (and recovery) of cod stocks is of great political and scientific interest An essential purchase for marine fisheries scientists Atlantic Cod: Bio-Ecology of the Fish is a vital book for all fisheries scientists, managers and fish biologists.

Book Description
This is the first report of the Circumpolar Biodiversity Monitoring Program (CBMP) to summarize status and trends in biotic elements in the arctic marine environment. The effort has identified knowledge gaps in circumpolar biodiversity monitoring. CBMP is the cornerstone program of Conservation of Arctic Flora and Fauna (CAFF).

Book Description
The devastation of many of the greatest North Atlantic cod stocks, particularly those of Newfoundland and Labrador and the Grand Banks, has become an icon for the unsustainable relation between human exploitation and Nature. Here, George Rose tells the full story of that devastation, in scientific detail, for the first time - from the formation of the North Atlantic marine ecosystems to the massive stock declines in the last half of the 20th century. Politics and the fisheries are inextricably entwined. In Cod, Rose recounts the many political influences on the fisheries over several centuries and describes how neglect from the late 1800s onward led to insufficient scientific knowledge and little protection for the stocks when massive Euro-Russian fleets targeted the Grand Banks after World War II, destroying the most prolific fishery the world has known. Cod is no armchair account, but a controversial one that includes original information on the North Atlantic fisheries.

Book Description
This book describes the marine ecosystem of the Barents Sea, located north of Norway and Russia as part of the Arctic Ocean. Basic knowledge is presented about components of the ecosystem from virus and bacteria via plankton and fish to seabirds through to marine mammals and their interactions with the physical environment. Ecosystem dynamics are given a prominent role in the book. Mathematical models of the plankton and important fish stocks are employed to help elucidate the interplay between populations and trophic levels. The situation regarding contaminants is reviewed, as is the newly established Norwegian plan for the management of the Barents Sea. The impact of global warming is also discussed. Ecosystem Barents Sea is written for all those with an interest in marine ecology in the arctic seas, including research institutes, governmental ecosystem management units, and natural resources organizations.

Book Description
This volume brings together current research on a wide range of swimming organisms, with an emphasis on the biomechanics, physiology and hydrodynamics of swimming in or on water. Several chapters deal with different aspects of fish swimming, from the use of different 'gaits' to the operation of the locomotor muscles. All chapters are by recognised authorities in their different fields, and all are accessible to biologists interested in aquatic locomotion.

Book Description
Quests for cod, herring and other sea fish had profound impacts on medieval Europe. This interdisciplinary book combines history, archaeology and zooarchaeology to discover the chronology, causes and consequences of these fisheries. It crosscuts traditional temporal and geographical boundaries, ranging from the Migration Period through the Middle Ages into early modern times, and from Iceland to Estonia, Arctic Norway to Belgium. It addresses evidence for human impacts on aquatic ecosystems in some instances and for a negligible medieval footprint on superabundant marine species in others (in contrast with industrial fisheries of the 19th-21st centuries). The book explores both incremental and punctuated changes in marine fishing, providing a unique perspective on the rhythm of Europe's environmental, demographic, political and social history. The 20 chapters - by experts in their respective fields - cover a range of regions and methodological approaches, but come together to tell a coherent story of long-term change. Regional differences are clear, yet communities of the North Atlantic Ocean and the Baltic, North and Irish Seas also followed trajectories with many resonances. Ultimately they were linked by a pan-European trade network that turned preserved fish into wine, grain and cloth. At the close of the Middle Ages this nascent global network crossed the Atlantic, but its earlier implications were no less pivotal for those who harvested the sea or profited from its abundance.
